一種可在堿性和酸性條件下高效析氫且具有納米海綿結(jié)構(gòu)的自支撐高熵金屬玻璃
- Inspired by the recently promising high-entropy concept with inherent multinary nature and glassy alloy with chemical homogeneity and tunability, we present a scalable strategy to alloy five equiatomic elements, PdPtCuNiP, into a high-entropy metallic glass (HEMG) for HER in alkaline and acidic conditions.
- Surface dealloying of the HEMG creates a nanosponge-like architecture with nanopores and embedded nanocrystals that provide abundant active sites to achieve outstanding HER activity.
- The obtained overpotentials at the current density of 10 mA cm-2 are 32 and 62 mV in 1.0 M KOH and 0.5 M H2SO4 solutions, respectively, outperforming most currently available electrocatalysts.
